Onager (Weapon)

The onager was a Roman torsion-powered siege engine, a type of catapult commonly built with a bowl, bucket, or sling at the end of its throwing arm. It was first mentioned in 353 AD by the historian Ammianus Marcellinus, who described onagers as the same weapon as a scorpion. The onager is often confused with the later mangonel, a traction trebuchet that replaced torsion-powered siege engines by the sixth century AD.
